摘要： An input signal Sx in a first millimeter-wave frequency band higher than 100 GHz is input to a millimeter-wave band filter 20 in which a pair of radio wave half mirrors 30A and 30B so as to opposite to each other and which performs a resonance operation. A signal component Sa corresponding to the resonance frequency of the filter is extracted, is mixed with a first local signal L1 with a fixed frequency, and is converted into a signal in a second frequency band. The converted signal component Sb is mixed with a second local signal L2 whose frequency is swept and is converted into a signal in a predetermined intermediate frequency band. Then, the level of the signal is detected. The millimeter-wave filter 20 has high selectivity characteristics in a frequency domain higher than 100 GHz and can change its passband center frequency.

摘要： The process eliminates image rays generated in a frequency converting device generating actual rays and image rays from frequency rays of an input signal. The frequency converting device comprising a mixer mixing the input signal and a signal provided by a local oscillator and a filter assembly filtering the mixed signals output by the mixer. In a first sweep and a second sweep, the frequency of the oscillator is varied and the signal level at the output of the frequency converting device is recorded for a set of converted frequencies. The second sweep is carried out so that the frequency of the actual ray generated in the second sweep by an input ray is the same as the frequency of the actual ray generated in said first sweep by said input ray, and the frequency of the image ray generated in the second sweep by an input ray is not the same as the frequency of the image ray generated in said first sweep by said input ray. Then, the process determines if a ray-including signal level was recorded both during the first sweep and the second sweep for at least one converted frequency and displays an indication of the presence of a ray for said at least one converted frequency on a screen only if said determination is positive.

Detector means (7) detects the time of occurrence (ti), the duration (ΔTi) and the maximum value (y′i) of several halfwaves of the filtered base band signal (y(t)). Envelope reconstruction means (6) reconstructs the envelope (E(@)) of the spectrum of the input signal (x(t)) by using an estimated amplitude at an estimated center frequency of each line of the input signal (x(t)). The estimated center frequency and the estimated amplitude are calculated from the time of occurrence (ti), the duration (ΔTi) and the maximum value (y′i) detected by the detector means (7) from the several halfwaves of the filtered base band signal (y(t)).

摘要： A method and a device for increasing the dynamic range and measuring accuracy of a measuring device for spectrum and/or network analysis images a high-frequency electronic signal within a frequency range into at least two spectra through a first frequency translation by means of a mixer of the measuring device. As a result of the first frequency translation, the spectrum of the high-frequency electronic signal is successively imaged within the resolution bandwidth (ΔFZF) of an intermediate frequency filter of the measuring device. At the same time, through a second frequency translation, every spectral line of interference signals generated in the measuring device comes to be disposed outside the resolution bandwidth (ΔFZF) of the intermediate frequency filter.

摘要： A spectrum analyzer includes a synchronizing signal input terminal (27A) and a sweep control signal generator (32) inserted between the synchronizing signal input terminal (27A) and a ramp address generator (23). In the case of making a frequency analysis of an input signal Sx which is a burst wave, a synchronizing signal SY, synchronized with the burst wave, is applied to the synchronizing signal input terminal (27A) from the outside and a sweep control signal SC which rises an arbitrary period of time after the synchronizing signal SY and has an arbitrary width is generated by the sweep control signal generator (32). The sweep control signal SC is applied to the ramp address generator (32), which sweeps, in each burst, a ramp voltage VR for controlling a local oscillator (16) and an address AD for effecting a write into a signal loading memory (19), and in the other periods the sweep is stopped.

摘要： A tracking YIG tuned filter-mixer circuit is provided. In the preferred embodiment, four YIG-tuned resonators are combined to provide a tracking filter-mixer with a switched input. Field coils produce a magnetic tuning field that is uniform over the four YIG resonators. The first YIG resonator acts as the first stage of the filter, and in combination with a PIN diode circuit switches the RF input signal either to an output port or into the succeeding stages of the filter mixer. The second YIG resonator acts as the second stage of the filter. The third YIG resonator acts as the third stage of the filter, and as a fundamental mixer for combining the input RF signal with a swept LO signal to produce the IF output signal. The fourth YIG resonator acts as a discrimintor, comparing the LO frequency to the filter tuning frequency to generate an error signal for the field coil drive circuit. A small magnetic field coil over the fourth YIG resonator produces an offset magnetic field, tuning the fourth YIG resonator to the swept LO frequency, above the other three resonators by the IF frequency, so that the three YIG resonators that comprises the filter stages track the LO but are tuned to the RF frequency.

摘要： Evaluating method and apparatus for a test voltage by use of a bandwidth-limited evaluation circuits. For evaluation of a measured signal dependent on a variable parameter, an identification is first undertaken with a broad-band evaluation circuit to determine whether an interesting sub-region of the overall variation region of the parameter has been reached. When this is the case, then a reduction of the bandwidth of the evaluation circuit and a reduction of the variation rate of the parameter occurs in order to be able to evaluate with high sensitivity in the interesting sub-region.
